urine smell from toddlers breath

hi all, just posting this to see if any of you can help with this. Recently i noticed my 3yo breath smells really bad, some days its stronger than others. Its been like this for about two months now and it finally hit me that it smells a bit like urine. So i googled it, big mistake as i was freaking out that he had some kidney troubles. I made an app with his doctor and she took a urine sample there and then which showed protein. This also suggests kidney problems. The sample was then sent off to lab for further testing and came back clear. After this result the smell seemed to go away for a few days but is now back again, i dont know what i should do, has anyone heard of anything like this before?

My son is 11 and has been having the same problem for over a year now - he brushes his teeth but after a few mins the smell is back again. It gets him down when I mention it so I try not to. Just hoping that he outgrows it

Hey Emma, Did you ever go to doctors about it. Im the same, i've kinda became obsessed with smelling for it, i feel sorry for him and dont want him to feel down about it either.
I take extra care when brushing his teeth but like you mentioned the smell just comes back straight away. I think i'll make another appointment on Monday .

Thanks for posting. You are concerned your 3 year old's breath smells of urine. You have consulted your GP and a urine sample has come back clear.

You have made a plan to go back to your GP on Monday which sounds like a sensible plan, particularly as it has come back again.
Sorry we can't offer any more advice at this stage, this is something best checked by a GP.
In the meantime continue with the careful brushing and keep up his fluid intake.

My 3 year old has this problem too, but he has a lot of pain associated with it, last night he woke up crying and was almost hyperventilating. He too has had the urine tests which came back clear. I am more worried as there is a history of a hereditary kidney disease in my family. Did any of you get to the route of the problem or did it go away by itself?
